It's nearing the end of a long Winter, and chances are high that you've been logging some indoor miles on the treadmill. Lately, I've been rocking a negative split run on the machine. This keeps me upping the speed of the treadmill as my workout moves along, but my average speed is 6.3 miles per hour. I know for some that this might feel like a snail's pace, but for others a wee bit fast — to each her own speed. When you're on the treadmill what's your average pace? Feel free to check this speed conversion chart if you need a little guidance.
